Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CD case reversing transfer device for reversing a thick CD case from a standing posture to a horizontal posture and supplying it to the next step.

[0002]

2. Description of the Related Art The work of packing a CD in a CD case is a process of opening the cover of the CD case sent on the case packing line, inserting the CD therein, and then closing the cover of the CD case. The closed CD case is transported to the subsequent process by the case packing line. Therefore, the CD case supplied to the case packing line must be in a horizontal position with the lid facing upward.

[0003]

However, since the CD cases supplied from the upstream of the case packing line are received in a long case bundle in which a large number of cases are stacked, the case bundle placed on the upstream side is Each CD case forming the bundle is in a standing posture. Therefore, in order to automatically supply the CD cases to the case packing line, it is necessary to automatically perform the operation of reversing the CD cases one by one from the bundle of CD cases to the horizontal posture and supplying them to the next process. . But from the case bundle C
The device that separates the D cases one by one and inverts them to supply
Since the structure is complicated and the size is large, the occupied floor area is large, and the manufacturing cost of the device is high. The present invention aims to solve such problems,
The present invention provides a reverse transfer device for a CD case, which has the advantages of a simple structure, compact size, and low cost.

[0004]

In order to achieve the above object, a reversing transfer device for a CD case according to the present invention is provided with a belt which is stretched around two pulleys, and a plurality of CDs are mounted on the belt. A belt conveyor on which a large number of cases capable of accommodating (compact discs) are arranged in an upright posture and arranged in the transport direction, and the case is located outside the center axis of the pulley on the carry-out side of the belt conveyor. A sensor for detecting that the conveyor surface is provided below the carry-out end of the belt conveyor, and a conveyor device having a pusher for pushing the case transferred on the conveyor surface in the conveyor direction, It is configured by a control unit that receives the detection signal of the sensor, stops the belt conveyor, and rotates the belt conveyor by the operation confirmation signal of the pusher, and the belt conveyor stops. Occasionally, transported case to the curved surface of the unloading end of the belt conveyor, falling in the conveyance surface in the state of a fall almost 90 degrees, it is characterized in that is transferred.

The carrying surface of the carrying device is composed of two rails, and a brush-like cushioning member may be provided on the surface of the rail at a position where the case is transferred. It is desirable that the tip end of the brush-shaped cushioning member be inclined in the direction of correcting the transfer position of the CD case that is dropped and transferred.

In the CD case reversing transfer device configured as described above, a large number of CD cases having a large thickness are transferred to the belt conveyor as a case bundle arranged in the conveying direction in a standing posture. . Since the belt of the belt conveyor is wound around the drive pulley and the driven pulley, both end portions of the belt conveyor have arcuate curved surfaces that gradually become lower than the conveying surface. In the case bundle placed on the conveying surface of the belt conveyor, each CD case is in a standing posture.

When the belt conveyor runs, the sensor detects that the CD case at the tip of the case bundle has reached the unloading side, and the belt conveyor stops. At this time, the case at the tip stops while remaining on the curved surface on the unloading end side of the belt outside the central axis of the pulley, so it is inclined toward the unloading end side by the inertia of traveling and its own weight while receiving the frictional force of the belt. , And is placed on the transfer surface of the transfer device by being turned over by approximately 90 degrees.

When the case is transferred to the conveying surface, the pusher pushes the case to convey the case, and after the pushing operation of the pusher is confirmed, the belt conveyor runs again and the next case does the same. Reprinted in reverse. In this way, the belt conveyor is intermittently conveyed, and the cases are transferred in reverse one after another.

The height of the carrying surface of the carrying device is slightly lower than the curved surface of the belt conveyor on the unloading side, and the amount of fall of the CD case is small. However, the portion on the upper side of the CD case in the standing posture has a large arc of a fall trajectory, and is the portion of the CD case where the impact of the fall is the largest. Although this impact is not great enough to damage the CD case, it may cause variations in the transfer position of the CD case, so on the transport surface, the area where the largest impact of the CD case drop is transferred. By providing the brush-shaped cushioning member, it is possible to reduce variations in the transfer position of the CD case.

Since the CD case dropped onto the cushioning member bounces, the end of the CD case may rest on the tip of the pusher, and the CD case may not be conveyed by the pusher. Tilt the tip away from the pusher to prevent the CD case from resting on the pusher.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the essential parts of a CD case inversion transfer device, and FIG. 2 is a case supply mechanism in which a CD case inversion transfer device is installed. FIG. 3 is a partially enlarged view of FIG. The inversion transfer device A for a CD case according to the present invention receives the case bundle 1 ′ from the case storage portion B on the upstream side and receives the case bundle 1 ′.
Is a device for reversing the CD cases 1 one by one to a horizontal posture and transferring them to the transport device C on the downstream side (see FIG. 2).

Along with the flow of the CD case 1, the structure of the case storage section B, the reverse transfer apparatus A, and the transfer apparatus C will be described in detail. The case storage section B has a large number of CD cases 1
Is arranged to receive and stock a long case bundle 1 ′ in which the
The case bundles 1'received are sequentially arranged and placed on the wide roller conveyor 2.

The roller conveyor 2 rotatably supports both ends of a plurality of shafts (not shown) on a pair of frames 3 which are arranged in parallel at intervals. When a shaft (not shown) is attached and the shaft is rotationally driven, the case bundle 1'on the rollers is conveyed at a low speed in the direction of arrow P (see FIG. 2).

At the carry-out end of the roller conveyor 2, a cylinder (not shown) moves up and down, and when it goes down, a lift table 4 which is lower than the transport surface of the roller conveyor 2 is provided close to the roller conveyor 2 with respect to the lift table 4. A square beam 5 is provided on the opposite side of. Since the upper surface of the square beam 5 is at the same level as that of the lift table 4 that has risen, when the case bundle 1 ′ on the roller conveyor 2 is transferred to the lowered lift table 4, it hits the square beam 5 and stops.

Inverting transfer device A in the direction of arrow P of square beam 5.
The belt conveyor 6 is provided. Belt conveyor 6
Has a carrying surface having substantially the same height as the upper surface of the square beam 5, and carries the case bundle 1 ′ in the direction of arrow Q. Belt conveyor 6
A cylinder 7 is disposed above the cylinder 7, and a scraping plate 8 is provided at the tip of the piston rod of the cylinder 7. The scraping plate 8 is at a height that does not hit the case bundle 1'on the roller conveyor 2 or the case bundle 1'on the lowered elevator 4.
The length of the scraping plate 8 is such that the case bundle 1'can be scraped at one time (see FIG. 2).

Normally, the piston rod of the cylinder 7 projects,
Although the scraping plate 8 projects up to the carrying-out end of the roller conveyor 2, when the case bundle 1 ′ mounted on the roller conveyor 2 is transferred to the elevating table 4 and the elevating table 4 rises, The piston rod of the cylinder 7 moves in the retracting direction, and the scraping plate 8 draws the case bundle 1 ′ on the lifting table 4 into the belt conveyor 6 of the reversing transfer device A via the upper surface of the square beam 5. As described above, the case storage section B for transferring the case bundle 1 ′ to the reverse transfer apparatus A is configured.

In the belt conveyor 6, a rubber belt 9 wound around a driving pulley and a driven pulley rotates in the direction of arrow Q shown in FIG. A light emitting / receiving sensor 21 for detecting the CD case 1 that has reached the outside of the central axis of the pulley on the unloading side of the belt conveyor 6 is provided. The sensor 21 is C
It detects that the D case 1 has reached the carry-out position, and when this detection signal is transmitted to the control unit (not shown), the belt conveyor 6 is stopped by a command from the control unit.

A carry-in section of a carrying device C having a carrying surface extending in a direction intersecting the belt conveyor 6 at a right angle and having a height lower than that of the belt conveyor 6 is provided near the carrying-out end of the belt conveyor 6. To do. The carrier C includes two rails 10 and a guide plate 1 provided outside the two rails 10.
1 and a pusher cylinder 12, and a pushing portion 14 fixed to the tip of the piston rod 13 of the pusher cylinder 12.
However, it projects in the direction of arrow R between the two rails 10 and conveys the CD case 1 on the two rails 10.

Of the two rails 10, a plurality of brush-shaped cushioning members 15 are arranged on the upper surface of the rail 10 farther from the belt conveyor 6. The tip of the brush 11 is shown in FIG.
Is inclined in the arrow R direction. Due to the protrusion of the piston rod 13 of the carrier device C, the CD case 1 on the two rails 10 is guided by the guide plate 11 and the case feeder device D.
Is fed to the accumulating conveyor 16 and the CD case 1 on the accumulating conveyor 16 is a single conveyor 1
7 and transferred to side pusher 19 and rear pusher 2
When 0, the CD cases 1 on the simplex conveyor 17 are supplied one by one to the downstream side.

Next, the operation of the reversing transfer device A for a CD case of the present invention will be described. A long case bundle 1'having a large number of CD cases 1 superposed on each other is placed on the belt conveyor 6 by the scraping plate 8. Since the belt 9 of the belt conveyor 6 is wound around the driving pulley and the driven pulley, both ends of the belt conveyor 6 are arcuate curved surfaces gradually lower than the conveying surface (see FIG. 1). The long case bundle 1 ′ placed on the conveying surface of the belt conveyor 6 faces the conveying direction of the belt conveyor 6, and the CD cases 1 forming the case bundle 1 ′ are in an upright posture.

When the belt conveyor 6 rotates and travels, the CD case 1 at the tip of the case bundle 1'reaches the flat end on the unloading side, and when the sensor 21 detects the CD case 1 at the tip, a detection signal is received. After the control unit has passed an extremely small time (this time difference can be finely adjusted by a timer), the belt conveyor 6 is stopped. Therefore, as shown in FIG. 1, the case 1 stops at the position of reference numeral 1 ″, which is placed on the curved surface slightly outside the central axis of the pulley of the belt conveyor 6.

Since the case 1 stopped at the position of reference numeral 1 "is located outside the central axis of the pulley, the inclination angle becomes approximately 90 degrees along the inclination on the carry-out end side due to the inertia of traveling and its own weight. And the conveyor C is separated from the belt conveyor 6.
It is placed on the rail 4 of. As shown in FIG. 1, the height of the rail 4 of the transport device C is slightly lower than the arcuate curved surface of the belt conveyor 6, so that the CD case 1
Is small.

However, at the portion on the upper side of the CD case 1 in the standing posture, the falling locus becomes a large arc, and C
This is the portion of D case 1 where the impact of the fall is the greatest. Although this impact is not so large as to damage the CD case 1, it causes variation in the transfer position of the CD case 1. However, the cushioning member 15 provided on the upper surface of the rail 4
Since the impact of dropping the CD case 1 is absorbed, it is possible to reduce variations in the transfer position of the CD case 1. Since the tip end of the brush-shaped cushioning member 15 is inclined away from the pusher cylinder 12, the CD case 1 bounced on the fitting member 15 may not be carried on the pushing portion 14 and may not be conveyed. Certainly prevented.
